npm install list-singly-linked``javascript
const LinkedList = require('list-singly-linked');
const list = new LinkedList(); // creates a new Linked List object
list.push(value) // appends a new tail node with given value
list.unshift(value) // appends a new head node with given value
list.pop() // removes the tail node from list and returns the removed node's value
list.shift() // removes the head from list and returns the removed node's value
list.get(index) // returns the node, defined by index
list.findIndex(callback) // returns the index of the first element in the list, that satisfies the provided testing callback function.
// Otherwise, it returns -1, indicating that no element passed the test
list.find(callback) // returns the value of the first element in the provided array that satisfies the provided testing function.
// If no values satisfy the testing function, undefined is returned.
list.length // the length of the list
